Hi,

and I added a 10 halo watts to ensure continuity of charge.
Replacing it with an 12 V 2 A adapter would have cost you less without having to consume 10 W unnecessarily;)

tophe59540It would be necessary to know the type of led and the power.
If they are provided in alternative and that the diode bridge is HS, you can simply remove these diodes and supply all with a 12 V DC adapter adapted to the total power of your LEDs.

but I remember the idea for next time.

- Oh yeah : Oops: ! 35W mini!
- But the solution to replace by a 50 Hz transformer still holds! Although less powerful, it is also less "looking" at the power than an electronic transformer! If there is room "under the hood" of the luminaire, it is an idea to exploit!
- But let's also look at the idea of ​​straightening the current of these electronic transformers by fast diodes, to put a self in series to lower the tension (that is practice on the output 3,5V in the power supplies of PC!) And a capacitor to smooth this voltage, provided of course that the power of the LED lamps reaches the minimum power required by the transformer!
- I have in front of me one of these LED lamps. Its power is 3x2W, which makes 6W Gold, by putting only 6 lamps, it makes 36w, if I'm not mistaken ! So already it exceeds the mini power of this transformer! My idea is not that bad, so!

I made a RGB ramp with 15 m ribbons leds, 900 leds powered with a reconverted old PC tower power supply at a very low cost;)

Hello

I am interested in the manipulation on the PC power supply: Should we simulate the presence of the motherboard?

Thank you

If it's an ATX, you have to connect the green wire and one of the black wires together on the 20 connector or 28 pins. Mine came out about 11 v in charge, I had to act on the regulation to raise it to 13 V. http://fr.wikipedia.org/wiki/Bloc_d'alimentation

So for the led I'm not I'm going to dismount one tomorrow I'll see
but it looks like a little classic diode that changes color with the remote as a night light
The thing is that there is not bad!
The luster comes from a German site I look to join them and no answer
even on the site hard to have precisions
http://lichtar.de/web/Deckenleuchten/Sc ... am=scoppio
and when you say it's the transfo jindel to change and you really sure
it is those who cause the differential to break?
Because I handed my halogen to see and it works and it is the white that manages the halo
I thought that his come black box on them is written led
and its disjunct that when I press to turn on the leds

Its mrepasse by the head when I go up the G4 LED Bulb Lamp AC / DC 12V 3W 48 LED SMD 3014 Warm white and cold
Image
the remote refused to work to believe that the swith did not want
Because when I ironed in halogen its refurbished then again when
I put back the LEDs worked more so I turn on the switch to the wall
Each pulse changed the position of the switch
and even after a few minutes ...
ps: when i'm feeding pc pc i say ksa is going to be impossible to fit in the chandelier
thank you for your help for fear I order a switch his my listening 12 €
We will see and then I look for transfo also but I need help thanks to you

To make sure, you can connect the led power supplies (black boxes) to the 230 V ~ sector one after the other and monitor the meter to see if there is over-consumption.
Is the chandelier connected to the ground wire? It can also be a possibility.

PS: The SMS writing is difficult to decipher!
